       <STRONG>beep</STRONG>, <STRONG>flash</STRONG> - ring the (visual) bell of the terminal with <EM>curses</EM>

       <STRONG>int</STRONG> <STRONG>beep(void);</STRONG>
       <STRONG>int</STRONG> <STRONG>flash(void);</STRONG>


</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       The  <STRONG>beep</STRONG>  and <STRONG>flash</STRONG> routines are used to alert the terminal user.  The
       routine <STRONG>beep</STRONG> sounds an audible alarm  on  the  terminal,  if  possible;
       otherwise  it  flashes  the  screen  (visible bell).  The routine <STRONG>flash</STRONG>
       flashes the screen, and if that is not possible, sounds the alert.   If
       neither  alert is possible, nothing happens.  Nearly all terminals have
       an audible alert (bell or beep), but only some can flash the screen.


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       These routines return <STRONG>OK</STRONG> if they succeed in beeping  or  flashing,  <STRONG>ERR</STRONG>
       otherwise.


</PRE><H2><a name="h2-EXTENSIONS">EXTENSIONS</a></H2><PRE>
       SVr4's  beep  and  flash  routines  always  returned  <STRONG>OK</STRONG>, so it was not
       possible to tell when the beep or flash failed.


</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       These functions are described in X/Open Curses, Issue 4.  Like SVr4, it
       specifies that they always return <STRONG>OK</STRONG>.
